i only want guys that have real experience on this plase, no thoughts just hard core facts.
now my question is does the JDM ITR header hang too low? i know the block height is like 7mm difference between b16 and b18 but does that cause misalignment problems with the cat.
i know i need a new 2 1/2" cat and blah blah blah but will it align properly?

also anyone have one for sale???

 

It lined up for me. except for the bracket that comes off the back of the motor to support the header. But its not necessary.

It did hang lower than stock but if you have stiff suspension and you are not dumped you wont have to worry about it.

 

oh yeah if you have a lower tie bar you may have some clearance issues. I had to cut one of the heat shield brackets off to clear my cusco piece.

 

Dude its cool....i have a jdm b16 with an itr header...it will line up fine...and won't hang too low...people with dc 4-1 headers have the low hanging prob

 

my jdm ITR header, hangs low in my b16, I had to raise my car about 1.75 inches... to get over the apartments speed bump

 

yikes speed bumps..now maybe that can be a prob....thank god there aren't but like two around here where i live........you might have to worry about those.....find a skid plate to buy and put it on before you put the header on it will pretect it from getting dented or scratched.

 

cool thanks for all the info, i have a dc SS 4-1 right now but i think im gonna upgrade to a JDM ITR

now i just need to find one for a good price

 

I had one on my 99 Si. Loved it. Bolted up perfectly with a Carsound 94006 from SMSP. As long as you have a 92+ Civic ground clearance won't be a problem as my oil pan hung lower.

88-91's have problems with ground clearance.
